I got sick of the maintenance on my KTM. Last week I rode 60 mi of Clear Creek on the 650R, yesterday 30 mi of Carnegie, today 45 miles of Hollister. I just got to the point I didn't want to adjust the KTM valves again, change the oil, etc. I rode mostly gnarly single track with my 13/51 gearing and IRC M5b. The gnarliest trails at Clear Creek, Happiness Valley at Carnegie and the MotoCross track, all the tracks at Hollister, did Troll trail 3 times. The piggie took it all and asked for more. One of these days I'll ride the KTM again, I suppose.
